2 Claims.

This invention relates to new and useful improvements in an adjustablerazor sharpener.

More specifically, the invention proposes the construction of a razorsharpener for adjustably supporting a pair of parallel stroppingelements so that they may be easily adjusted by merely turning a handlefor controlling the tensioning thereof.

Still further it is proposed to so construct the device that the stropelements may be supported thereon, one with the smooth side out and theother with the rough side out for providing a choice of surfaces againstwhich the razor may be engaged.

Still further it is proposed to characterize the razor sharpener by apair of parallel rods having spacer plates mounted thereon, one of whichis fixed and the other of which is slidable, and to stretch the stropperelements between the spacer plates so that when the adjustable plate ismoved it will control the tension of the strop elements.

A still further object of this invention is to provide a means wherebythe strop elements may be adjusted to various tensions individually ofeach other.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. '7 is a sectional view on the line 1-1 of Fig. 6.

The adjustable razor sharpener, according to this invention, comprisesparallel rods l0 and H having reduced end portions. The rods I0 has itsends Ill and 18 reduced and the rod II has its ends H and ll reduced. Apair of spacer blades 12 and I3 are mounted on the shoulders at the endsof the rods I0 and H. The plate I2 is mounted on the reduced ends Illand H of the rods l0 and H. The other plate I3 is slidably mounted onthe rods 10 and II. This spacer plate I3 is adapted to be moved alongthe entire 5 length of the rods l0 and II.

A member I4 is mounted on the reduced ends N and H of the rods [0 and H.The member I 4 and the spacer plate [2 are adapted to hold the rods H]and l l in their spaced parallel posi- 0 tions. A pair of parallel stropelements !5 and it are mounted across the edges of the spacer plates 12and I3. The strop elements 15 and It are constructed from lengths ofleather and have their ends bent at right angles to the body 15 portionthereof and superimposed one upon each other adjacent the outer faces ofthe spacer plates I2 and I3.

A means is provided on one of the spacer plates for gripping and holdingone of the ends of the strop elements. The ends l5 and i6 of the stropelements l5 and [6 are superimposed on each other adjacent the outerface of the spacer plate E2. The reduced ends I!) and ll pass throughopenings l5 and I6 formed in the ends |5 and Hi A clamp element H ispositioned upon the end l6 of the strop element W. A screw l8 passesthrough aligned openings formed in the center portions of the clamp element Iii, the ends l5 and Hi and threadedly engages an opening formed inthe center of the spacer strip !2. This screw I 8 is adapted to betightened for urging the clamp element H into a position in which itwill force the ends I 5 and l6== tightly against the outer face of thespacer strip l2.

Means is provided on the other spacer plate for gripping and holding theother ends of the strop elements l5 and I 6. The ends l5 and It of thestrop elements l5 and I6 are superimposed on each other on the outerface of the spacer plate l3. The end [5 if formed with openings l5 andthe end la is formed with openings [5. The rods l0 and H are adapted toslidably engage through the openings lfi and I E A clamp element I9 isslidably supported on the rods I0 and H and is adapted to abut againstthe overlapping ends lb and 16 for urging these ends tightly against thespacer plate l3. A screw 20 passes freely through aligned 5 openingsformed in the member M, the clamp element [9 and the ends I5 and 16 Thescrew 26 threadedly engages an opening formed in the spacer plate l3. Alook nut 2| is threadedly engaged upon an intermediate portion of thescrew to move the spacer plate I3 along the length of 20 and is adaptedto be tightened against the clamp element I9 for urging it tightlyagainst the ends I5 and lfi A handle 22 is mounted on one endof thescrew 20 for moving the slidable spacer plate I3 towards the member I4when the handle is rotated for tightly stretching the strop elements I5and I6 between the spacer plates I2 and. I3. The handle 22 is fixedlysecured at one end to one end of the screw 20 and when the handle 22 isrotated in the proper direction it is adapted the rods I83 and II awayfrom the spacer plate l2 and toward the member I4. When the spacer plateI3 moves towards the member I4 it tightly stretches the strop elementsI5 and I6 between the plates I2 and I3. The handle 22 normally abutsagainst the outer face of the member I4 for limiting its movement withrelation to the rods I0 and II.

The operation of this device is as follows:

The ends I5 and I6 of the strop elements l5 and I6 are securely attachedbetween the spacer plate l2 and the clamp element I! by engaging thescrew I8 through these parts. The ends I5 and W of the strop elements I5and I6 have been slidably engaged on the intermediate portions of therods Ill and H with the spacer plate insertedbetween the adjacent facesof the strop elements l5 and It. The clamp element I9 is then slidablyengaged upon the rods Id and II p and the member M is engaged on theends Ill and I I of the rods. The screw 2% is then passed through themember I l and the lock nut 2I positioned thereon. The screw 28 is nextpassed through the aligned center openings of the clamp element I9 andthe ends l5 and I6 Then the screw 20 is threadedly passed through thecenter opening formed in the spacer plate I3. The handle 22 is rotatedto move the spacer plate I3 away from the plate I2 for tautly stretchingthe strop elements between the plates I2 and I3.

After the strop elements I5 and It have been properly tensioned the locknut 2I is rotated along the length of the screw until it tightly urgesthe clamp element I9 against the ends ifi and it of the stropelements-Ashe sharpener is then in position for sharpening a razor.

If the strop elements 55 and 56 should stretch or become loose betweenthe plates I2 and I3 they may be further tensioned by moving the locknut 2! out of contact with the clamp element I9 and then the handle 22may be again rotated to space the plate i3 further away from the plate52 to again tension the strop elements to compensate for the stretching.

According to the modification shown in Figs. 6 and 7 a provision is madefor adjusting the strop elements I5 and I6 individually of each other.This means comprises a strip element 23 adjustably mounted on one edgeof the plate IE; and engageable against the strop element I5 fortightening the strop element E5 to a greater degree than the stropelement it. The adjustable supporting of the strip element 23 compriseslugs 2d formed upon the strip element. These lugs 24 are integrallyformed with screws 25 which are adapted to slidably engage through lugs26 formed on the plate it immediately below the lugs 24. The lugs 25 areformed with openings 26 through which the screws 25 are slidablyengaged. Nuts 27 are threadedly engaged upon an intermediate portion ofthe screws 25 and are adapted to abut the top face of the lugs 261 forholding the screws 25 in various adjusted positions with relation to thelug 26 for moving the strip 23 away from the plate I3., Lock nuts 28 arethreadedly engaged upon the ends of the screws 25 and are adapted toabut the bottom end of the lugs 26 for fixedly holding the screws 25 intheir adjusted positions.

The operation of this form of the device is as extend the screws 25 withrelation to the lugs 26.

These screws 25 are fixedly attached to thelugs 24 and when the nuts 23are rotated they will extend the screws 25 causing the strip element 23to move away from the plate I3 to tension the strop element I5 toagreater degree than the strop element I6. In other respects this formof the invention is similar to the previous form.

While I have illustrated and described the pre-' ferred embodiments ofmy invention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desireto'secure by United tates Letters Patent is: I
